If you want to call/execute the anonymous functionyou will have to add a pair of parentheses to the variablemyFunclikemyFunc();As the anonymous function was defined as having 2 parametersyou have to provide 2 argumentsin our case 2 string VALUES "Alena" and "Lauren"likemyFunc("Alena","Lauren");

some quotes from the outer-world:

**argument is the value/variable/reference being passed in, parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters", while "arguments" are called "actual parameters".**

you have defined a myFunctionfunctionwhich takes 1 parameterparam1this param1parameter is used as a variable throughout the FUNCTION-BODY.

If you want to call/execute this myFunctionfunctionand this myFunctionfunction was definedas having 1 parameterparam1you will have to provide 1 argumentin our case a "number VALUE" 4myFunction( 4 );

**argument is the value/variable/reference being passed in, parameter is the receiving variable used within the function/block**

**"parameters" are called "formal parameters", while "arguments" are called "actual parameters".**

============================================

As you are using the return-statement in your myFunctionfunctionyou will only get a return-value no-display.You can however capture this return-value in a variableand then use the console.log()-method to do a display.
